Parasitology (Exam 1 Kahoot)

This flagellated protozoan infects many mammalian hosts and is associated with small bowel diarrhea

Giardia duodenalis

A 3mo beagle has loose mucoid stools, what diagnostic should you perform?

Direct smear with saline (fresh sample can reveal trophozoites)

Zinc sulfate solution can reveal cysts

Saturated sugar or sodium nitrate will reveal cysts but collapse them

In clinical cases of Balantioides coli, lesions are most often limited to this organ

Large intestine, colon, cecum, etc

Neonatal porcine coccidiosis is associated with diarrhea and wasting in young pigs and is caused by infection with ____________

Cystoisospora suis

This ciliated protozoan infects freshwater fish and causes the disease known as "white spot"

Ichthyophthirius multifiliis

Managing these protozoans is difficult because infected hosts shed stages that are immediately infectious in fresh feces

Giardia duodenalis and Tritrichomonas foetus

The detection of these protozoans are enhanced by culturing in growth media of InPouch

Tritrichomonas foetus and Trichomonas gallinae

True or false: Eimeria species are not host specific

False

Provide a single protozoan (genus) that produces immediately infectious cysts that are passed in fresh feces

Giardia or Balatioides

Histomonas meleagridis produces grossly visible lesions in these 2 organs in an infected turkey

Liver and cecum

True or false: Bulls infected with Tritrichomonas foetus will eventually clear infections and do not display over clinical signs

False (will not clear infection)

Which of the following protozoans have zoonotic potential?

Giardia duodenalis

Balantioides coli

Trichomonas gallinae

Eimeria zuernii

Giardia duodenalis

Balantioides coli

Histomonas meleagridis is usually transmitted indirectly by the involvement of this cecal nematode (genus and species)

Heterakis gallinarum

The best medium to perform a direct fecal smear is ____________

physiological saline

True or false: Cats and dogs may become infected with Eimeria spp. if they consume sporulated oocysts in contaminated H2O or food

False (Eimeria does not infect dogs or cats)
